#How is the certainty of an apparent cure in ringworm of the scalp or bearded region to be determined?# By the continued absence of roughness and of broken hairs and stumps, and by microscopical examination of the new-growing hairs from time to time for several weeks after discontinuance of treatment. Cure of ringworm of the general surface is usually self-evident. #Is systemic treatment of aid in the cure of ringworm?# It is doubtful, although in children in a depraved state of health the disease is often noted to be especially stubborn, and in such cod-liver oil and similar remedies may at times prove of benefit. #Tinea Imbricata.# (_Synonym:_ Tokelau Ringworm.) #What is tinea imbricata?# A vegetable parasitic disease of moist tropical countries, characterized by the formation of patches composed of concentrically arranged, imbricated, scaly rings. It may begin at one or several points as a brownish, slightly raised spot, spreading peripherally; the renewed epidermis of the central part of the patch goes again through the same process; the result is a small or large area of concentrically arranged, imbricated, slightly scaly eruption. Several such areas fusing together may cover a large part of the surface, the ring-like arrangement being sometimes more or less completely lost. The malady is chronic. There may be a variable degree of itching. The cause of the disease, which is of a contagious nature, is a vegetable parasite closely similar to the trichophyton. The treatment is by the parasiticides, being essentially the same, in fact, as ringworm. #Tinea Versicolor.# (_Synonyms:_ Pityriasis Versicolor; Chromophytosis.) #What is tinea versicolor?# Tinea versicolor is a vegetable-parasitic disease of the skin, characterized by variously-sized and shaped, slightly scaly, macular patches of a yellowish-fawn color, and occurring for the most part upon the upper portion of the trunk. #Describe the symptoms of tinea versicolor.# The disease begins as one or more yellowish macular points; these, in the course of weeks or months, gradually extend, and, together with other patches that arise, may form a more or less continuous sheet of eruption. There is slight scaliness, always insignificant and furfuraceous in character, and at times, except upon close inspection, scarcely perceptible. The color of the patches is pale or brownish-yellow; in rare instances, in those of delicate skin, there may be more or less hyperaemia, and in consequence the eruption is of a reddish tinge. The number of patches varies; there may be but a few, or, on the other hand, a profusion. Slight itching, especially when the parts are warm, is usually present. #Does the eruption of tinea versicolor show predilection for any special region?#
